They have other sizes as well. I have been using Spectra cable since 1997 on our robots for all kinds of lift and winch functions. It has never failed us.

Raul the Magnificent!

Thanks.

By the by, what is the breaking strength of the 1.9mm Spectra string?

Usually in the neighborhood of 500-600 lbs (tensile). Be aware that a knot will drop the strength by as much as 50%, and that you should use a thimble to prevent it from kinking and chafing unless you're going around a solid shaft. Spectra is notorious for chafing (even though it is more chafe resistant that other aramids).

Are there any better/stronger crimps than those available through SmallParts and the ones that come with the cable?
